プＳ１）。Next, the operation will be described. FIG. 3 shows FIG.
3 is a flowchart showing the operation of the moving handrail tension adjusting device. First, the moving speed of the moving handrail 1 detected by the speed sensor 4 is input to the calculating unit 14 of the control unit 13.
The calculation unit 14 compares and calculates the moving speed of the moving handrail 1 and the preset speed (rated moving speed) input in advance, and determines whether the moving speed is equal to or higher than the set speed (step S1).

力も強くなり、移動速度が速くなる。As a result, if the moving speed is equal to or higher than the set speed, the tension of the moving handrail 1 is fixed as it is (step S
2) Then, the moving speed is continuously detected. When the moving speed is lower than the set speed, a signal is output to the drive unit 12 of the handrail tensioning device 11, and the tension of the moving handrail 1 is strengthened so that the moving speed becomes the set speed (step S).
3). As a result, the frictional force between the moving handrail 1 and the drive sheave 2 also becomes stronger, and the moving speed becomes faster.

Within the adjustment limit of the handrail tensioning device 11, the moving speed of the moving handrail 1 can be automatically maintained at a set value or more without stopping the operation of the escalator, so that a passenger may fall due to an emergency stop. In addition to being prevented, the passenger transportation efficiency of the escalator is improved. Also, the tension adjustment work during maintenance and inspection is reduced. Furthermore, since the handrail tensioning device 11 is provided with the limit switch 18, the adjustment limit of the handrail tensioning device 11 can be easily detected, and the safety is further improved.
